Or how about adding new boolean parameter of pg_stop_backup() that
specifies whether WAL archiving needs to be waited?
   pg_stop_backup([wait boolean])

This parameter is optional. If true (default), it waits for archiving.

In warm-standby and SR, we don't need to wait for archiving before starting
the standby from the base backup. So pg_stop_backup(false) would be
useful for speedup of setup of log-shipping.
